Driving method of pixel

Abstract

The invention discloses a pixel driving method, which comprises the steps as follows: firstly, to identify the first predetermined gray scale and the second predetermined gray scale corresponded with the target gray scale based on the target gray scale of the pixel. The sum of the said two predetermined gray scales together with the total equivalent gray scale is the same as the said target gray scale; secondly, the first driving voltage and the second driving voltage are generated based on the said two predetermined gray scales to respectively drive the two sub-pixels of the said pixel within one picture time. If the said equivalent gray scale is less than the first setting gray scale, the said first driving voltage will be higher than the said second driving voltage, while the said first driving voltage will be lower than the said second driving voltage if the said equivalent gray scale is more than or equal to the said first setting gray scale.

Description

technical field [0001] The invention relates to a driving method of a flat panel display, in particular to a pixel driving method capable of making a liquid crystal display have low color shift characteristics. Background technique [0002] Liquid Crystal Display (LCD) has gradually become the mainstream of the market due to its superior characteristics such as high image quality, good space utilization efficiency, low power consumption, and no radiation. At present, the performance requirements of the market for liquid crystal displays are oriented toward high contrast ratio, fast response, and wide viewing angle, and current technologies that can meet the wide viewing angle requirements such as multi-domain vertical alignment (Multi-domain Vertically Alignment, MVA) , Multi-domain Horizontal Alignment (MHA), Twisted Nematic plus wide viewing film (TN+film) and In-Plane Switching (IPS). [0003] FIG. 1 shows the gamma curve (gamma curve; hereinafter referred to as the side...

AI Technical Summary

Problems solved by technology

[0005] However, since the bright one of the above two sub-pixels is always bright, and the dark one is always dark, under the condition of following this kind of solution, the color cast of the low-grayscale and high-grayscale colors will be improved better, but The color cast of mid-to-high grayscale colors can be improved quite limited

Therefore, when the components of the image screen displayed by the LCD display occupy most of the middle and high grayscale colors, the color shift problem of the large viewing angle of the LCD display will still be quite serious.
